The “embedded_profile_len()” function in pngwutil.c does not check for negative values, resulting in a memory leak (CVE-2009-5063).
The “png_format_buffer()” function in pngerror.c contains an off-by-one error (CVE-2011-2501).
The “png_rgb_to_gray()” function in pngrtran.c contains an integer overflow error (CVE-2011-2690).
The “png_err()” function in pngerror.c contains a NULL pointer dereference error (CVE-2011-2691).
The “png_handle_sCAL()” function in pngrutil.c improperly handles malformed sCAL chunks(CVE-2011-2692).
The “png_decompress_chunk()” function in pngrutil.c contains an integer overflow error (CVE-2011-3026).
The “png_inflate()” function in pngrutil.c contains and out of bounds error (CVE-2011-3045).

Workaround :

There is no known workaround at this time.

Solution

All libpng 1.5 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/libpng-1.5.10' All libpng 1.2 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/libpng-1.2.49' Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
